Key Features

  • Dual independent comparator channels in a single 8-pin SOIC package halve component count in two-threshold detection applications compared to single-channel alternatives
  • Push-pull output stage directly drives logic inputs and small loads up to the supply rail without requiring an external pull-up resistor
  • Wide 2.7 V to 16 V supply range allows the TSX3702IDT to operate from single-cell Li-ion, 5 V logic, or 12 V industrial rails in the same standard footprint

Applications

The TSX3702IDT is used in window comparator circuits, overvoltage and undervoltage protection, and level-shifting applications in consumer electronics, industrial control panels, and battery management systems. Its dual-channel push-pull output and wide supply range make it a cost-effective choice for power supply supervisors, zero-crossing detectors, and signal conditioning stages in motor drive and lighting control designs.

Frequently Asked Questions

What is the response time of the TSX3702IDT, and how does that affect time-critical comparator applications?

The TSX3702IDT has a nominal response time of 2.4 µs, which means it can detect threshold crossings at signal rates up to approximately 200 kHz without significant delay distortion. For slower signals such as power supply ramp monitoring or temperature threshold alarms, the 2.4 µs latency is negligible, making it suitable for most industrial and consumer protection circuits.

What supply voltage range does the TSX3702IDT support, and can it operate from a single Li-ion battery?

The TSX3702IDT operates from 2.7 V to 16 V single supply, covering the full discharge range of a single-cell Li-ion battery (2.7 V to 4.2 V) as well as 5 V logic, 9 V alkaline, and 12 V automotive and industrial supply rails, all from the same 8-pin SOIC footprint without any circuit redesign.

How does the TSX3702IDT's push-pull output simplify design compared to open-drain comparators?

Unlike open-drain outputs that require a pull-up resistor to set the logic high level, the TSX3702IDT push-pull stage actively drives both output states to within millivolts of the supply rails. This eliminates 2 external resistors in a dual-channel design, improves output rise time to below 1 µs at 100 pF load, and prevents the output from floating in the presence of bus contention or resistor failure.

What is the maximum input offset voltage of the TSX3702IDT, and when does it limit detection accuracy?

The worst-case input offset voltage is 6 mV (6000 µV). For threshold detection where the input signal crosses a reference by more than 20 mV, the 6 mV offset contributes less than 30% error on the detection window; however, for precision window comparator applications requiring better than ±5 mV accuracy, an offset-trimmed part with 1 mV to 2 mV maximum offset should be considered instead.
